New style for Header and Sidebar

Plese, help me understand, where to find the files to correct them for managing Header and Sidebar styles.
P.S. in OJS 3
Thanks!

Hi @ashotgev,

If you just want to make CSS changes, I’d suggest uploading a custom CSS file to the Appearance area of settings that overrides the styles you want to change.

Hi, @asmecher, this is not exactly what I want, but I will be very grateful to you, if you sent me a link, where i can learn, how to make CSS changes. I mean which ID NAMES what does mean, which CLASS NAMES what does mean, etc.

Hi @ashotgev,

That’s beyond the scope of this forum, but there are lots of good CSS tutorials online, e.g.: CSS Tutorial

I’d suggest using a developer tool like Firebug for Firefox to explore the various class names and markup used in OJS.
